Argument: Geoengineering can effectively fight climate change

Issue Report: Geoengineering


In the New York Times, Ken Caldeira, of the Global Ecology Department at Stanford writes: “If we could pour a five-gallon bucket’s worth of sulfate particles per second into the stratosphere, it might be enough to keep the earth from warming for 50 years. Tossing twice as much up there could protect us into the next century.” Other experts say that blocking 2% of the sun’s rays from hitting the earth could stop global warming.
